The Pentagon Is Writing $1 Billion Checks — But Only to Fund Managers, and the Deadline Is November 1

Most federal funding announcements ask the same question: what will you build, and how much do you need? The Office of Strategic Capital's newest offering asks a different one entirely — how much private capital have you already raised, and can you prove you know how to lend it?

The Department of War's Office of Strategic Capital (OSC) posted the application for its National Security Fund Finance (NSFF) Program on August 20, 2026. Complete proposals are due November 1, 2026, at 5:00 p.m. ET. Individual facilities run $500 million to $1 billion. OSC expects to select applicants for due diligence by January 10, 2027, and to issue conditional commitments on or before March 10, 2027.

Those numbers put NSFF among the largest single federal financing offerings open this fall. They also make it one of the most misread. Nearly every organization that sees "critical minerals" and "$1 billion" in the same sentence is ineligible, and understanding precisely why is more useful than the headline.

This is a loan to a lender, not a grant to a builder

NSFF is what the capital markets call a fund finance facility. OSC does not lend to the mining company, the refinery, or the magnet manufacturer. It lends to a professionally managed U.S. debt investment fund, which then combines the OSC facility with its own private capital and makes loans into portfolio companies addressing national-security shortfalls in critical minerals and materials.

The instrument is a multi-draw term loan credit facility. The facility size is capped at the lesser of the amount requested or 125 percent of total fund equity — so a fund that has raised $600 million in equity commitments cannot request a $1 billion facility and expect it. The arithmetic caps you at $750 million, and that is a ceiling, not an entitlement.

Downstream, the fund's advances must be structured as first-lien or second-lien senior secured loans. Equity investment is generally prohibited. This is a debt program end to end: OSC lends to a debt fund so the debt fund can lend to companies.

That structure explains the government's motive. A direct-loan program scales at the speed of the government's own underwriting staff. A fund-finance program scales at the speed of the private credit market, which is considerably faster and already employs people whose entire job is diligencing mineral-processing balance sheets. OSC buys leverage on other people's underwriting capacity.

The eligibility bar, stated without euphemism

To submit, an applicant must be a debt investment fund duly formed under U.S. law, registered in SAM, and able to demonstrate:

• A minimum target fund commitment of $500 million
• At least 35 percent raised at first close
• Substantial U.S. operations, assets under management, and investment track record
• Documented cybersecurity practices
• Relevant SEC registrations where applicable

Read that list again. The floor is a half-billion-dollar target fund with $175 million already committed. There is no emerging-manager track, no small-fund set-aside, no first-time-fund carve-out. The population of U.S. private credit managers who clear that bar and want a 100-percent critical-minerals mandate is small — likely dozens, not hundreds.

If you are a nonprofit, a university, a startup, a state agency, or a project developer, you are not the applicant here. You may be the eventual beneficiary, which is a different and still useful thing.

The mandate constraints are tighter than the dollar figures suggest

The program documents impose a 100 percent critical-minerals focus on all advances — the fund cannot use an OSC-backed facility to drift into adjacent industrials. Layered on top:

• No solely defense-focused technologies. The portfolio must be dual-use. A company whose only customer is the Department of War is, counterintuitively, a poor fit for a Department of War credit facility. OSC's entire thesis is that national-security supply chains survive on commercial demand, not on procurement line items.
• No federal-government-dominated sectors, for the same reason.
• Portfolio concentration capped at 8.5 to 10 percent per company group, forcing genuine diversification across at least ten-plus positions.
• Prohibited dealings with sanctioned entities and foreign adversaries.

The dual-use requirement is the one that reshapes deal flow. It means the companies most likely to receive NSFF-backed debt are those with civilian revenue — data-center and semiconductor supply chains, aerospace components, energy storage — that happen to also resolve a defense vulnerability. Scandium, gallium, rare-earth magnets, and battery-grade materials all sit in that overlap. Pure-play defense subcomponents do not.

Evaluation rewards a boring, cooperative applicant

OSC says it will assess proposals on economic and national-security alignment, a proven investment strategy, firm structure, creditworthiness, and likelihood of reaching a definitive agreement — with stated preference for firms that accept the proposed terms as written.

That last clause is the tell. This is a credit process, not a peer review. A fund that submits a heavily marked-up term sheet signals a long negotiation, and a long negotiation threatens the March 10, 2027 conditional-commitment date OSC has publicly committed to. The applicant who takes the paper as drafted gets scored up for it. Anyone who has run a competitive grant process will find this jarring; anyone who has closed a credit facility will find it entirely normal.

Where NSFF sits in OSC's larger machine

NSFF is not a standalone experiment. OSC has been building a credit portfolio through 2026:

• Its first loan ran through the Department's agreement with MP Materials, anchoring the domestic rare-earth magnet chain.
• On August 7, 2026, OSC announced a conditional loan commitment of $400 million to Sunrise Energy Metals for scandium operations in New South Wales — a mineral that matters simultaneously to aerospace, semiconductors, and data centers, which is precisely the dual-use profile the office favors.
• It also runs the SBICCT investment-fund-financing initiative on the equity-adjacent side.

NSFF is the wholesale channel added on top of that retail lending. And the timing is not coincidental. DOE announced $500 million across seven critical-minerals projects on August 20, 2026 — awards of $50 million to $100 million covering lithium extraction and refining, cobalt refining, silicon-anode manufacturing, and lithium-metal films — and has since issued a Notice of Intent for PROSPECT (DE-FOA-0003662). A Common Investment Initial Screening Application, launched July 24, 2026, now routes projects across 14 federal financing partners.

The federal government has stopped treating critical minerals as a grant problem and started treating it as a capital-stack problem. Grants de-risk the science. Credit facilities build the plants.

What the ineligible majority should actually do

If you cannot apply to NSFF, three moves follow directly from its existence:

1. Identify which funds are applying, and get into their pipeline. Every dollar OSC commits in March 2027 becomes a fund manager's obligation to deploy. Those managers will need first-lien-quality borrowers with dual-use revenue inside a 100-percent-critical-minerals mandate. A project developer who is diligence-ready in Q2 2027 is meeting a buyer with a government-subsidized cost of capital and a clock. That is the single best moment to be raising project debt in this sector.

2. Structure toward senior-secured-loan eligibility now. First-lien debt requires clean collateral, unencumbered assets, an audited financial history, and a revenue story that does not depend entirely on federal procurement. If your capital plan assumes grant equity forever, you will not clear a credit committee. Fix that in 2026, not in 2027.

3. Use grants for the stage credit cannot reach. OSC does not fund bench-scale chemistry. DOE's ASPECT solicitation (DE-FOA-0003647, $58 million, concept papers due October 9, 2026) and the forthcoming PROSPECT NOFO do. The honest reading of the federal landscape is a relay: agency grants carry a technology from proof-of-concept through pre-pilot, then credit programs — OSC's, DOE's, and the 14-partner financing network — carry it to commercial scale. Applicants who map their own technology onto that relay stop writing proposals to the wrong window.

The deadline that actually binds

November 1 is a hard date for perhaps a few dozen firms. For everyone else in critical minerals, the operative dates are January 10 and March 10, 2027 — when the identity of the newly capitalized lenders becomes public and their deployment clocks start.

Federal funding for this sector is migrating from appropriated grant dollars to credit authority, and credit authority has different gatekeepers, different diligence, and a different definition of a good applicant. The organizations that adjust to that shift early will find money available on terms that grant programs cannot match. The ones still waiting for a NOFO that matches their old assumptions will keep finding closed windows.
